    Effect of Electroacupuncture on Hippocampal Functional Activity and Molecular Expression Profile in Rats with Vascular Cognitive Impairment by WANG Zeyu, DING Yanyi, DAI Yaling, YANG Minguang, HUANG Jia, ZHANG Shenghang

    Published 2021-12-01
    “…Barnes maze test was used to evaluate the spatial learning and memory ability of rats; Y maze test was used to evaluate the spatial working memory ability of rats; small animal 7.0 T magnetic resonance resting brain functional imaging was used to analyze the changes of regional homogeneity (ReHo) of hippocampal functional activity; Agilent mRNA expression microarray was used to analyze the differential gene expression of the whole hippocampus genome.Results① Behavioral analysis results: compared with the sham operation group, the Barnes maze escape latency of the model group increased significantly (<italic>P</italic>&lt;0.05), the target quadrant duration percentage decreased significantly (<italic>P</italic>&lt;0.05), and the Y maze alternation rate decreased significantly (<italic>P</italic>&lt;0.05); compared with the model group, the Barnes maze escape latency of the electroacupuncture group decreased significantly (<italic>P</italic>&lt;0.05), the target quadrant duration percentage and the Y maze alternation rate increased significantly (<italic>P</italic>&lt;0.05). ② ReHo changes results: compared with the sham operation group, the ReHo of functional activitives of the bilateral prefrontal lobes, hippocampus and other brain regions in the model group decreased significantly (<italic>P</italic>&lt;0.005); compared with the model group, the ReHo of functional activities of the bilateral hippocampus, prefrontal lobes and piriform cortex in the model group increased significantly (<italic>P</italic>&lt;0.005). ③ Genomics results: a total of 705 genes with 2-fold differential expression of hippocampal mRNA between the model group and the sham operation group (<italic>P</italic>&lt;0.05), of which 195 genes (such as Sytl1, Trpv6, Klhl14, Npsr1, Myh3, Galnt3, Nr4a1, Bmp3, Egr2, etc.) were down-regulated, of which 510 genes (such as Insl6, Efcab1, Akr1b1, Tagln, Glrb, Akr1c13, Kcne1L, Ubap1, etc.) were up-regulated. A total of 399 genes with 2-fold differential expression of hippocampal mRNA between the electroacupuncture group and the model group (<italic>P</italic>&lt;0.05), of which 166 genes (such as Klhl14, Bmp3, Npsr1, Cacna1e, etc.) were up-regulated, of which 233 genes (such as Insl6, Ube2k, Cdkn1c, Camp, Upk1b,etc.) were down-regulated.ConclusionThe "Tongdu Tiaoshen" electroacupuncture at Baihui and Shenting acupoints can improve the cognitive function of rats with vascular cognitive impairment, and its mechanism may be related to enhance the function of hippocampus, prefrontal lobes and other brain regions, regulate the expression of calcium ions and energy metabolism-related molecules by regulating nerve activity activity.…”

    Chemical Composition and Larvicidal Activity of Flower Extracts from Clitoria ternatea against Aedes (Diptera: Culicidae) by Darvin R. Ravindran, Madhuri Bharathithasan, Patmani Ramaiah, Mohd Sukhairi Mat Rasat, Dinesh Rajendran, Shakila Srikumar, Intan H. Ishak, Abd Rahman Said, Rajiv Ravi, Mohamad Faiz Mohd Amin

    Published 2020-01-01
    “…Hence, the major focus of this study is to identify the larvicidal mechanisms, metabolite, antioxidants, and chemical compounds and elucidate their structures from C. ternatea flower and to test their efficacies against early 4th instar larvae of Aedes aegypti and Aedes albopictus. …”

    Correlación entre desarrollo del pimpollo floral y el estadío de uninucleado a binucleado en Capsicum chinense "ají mochero" by Martín Giovanni Saavedra-Saldaña, Segundo Eloy López-Medina, José Mostacero-León, Juan Carlos Rodríguez-Soto, Armando Efraín Gil-Rivero, Anthony J. De La Cruz-Castillo, Roger Veneros-Terrones

    Published 2024-04-01
    “…Se concluye que existe una correlación positiva entre el desarrollo del pimpollo floral y el estadío a binucleado de C. chinense "ají mochero", por tanto, los pimpollos que poseen corola ligeramente más pequeña que el cáliz, son ideales para iniciar un proceso de androgénesis, el cual contribuiría con el mejoramiento genético de C. chinense al obtenerse líneas puras. …”
